Summary of the invention
The purpose of this utility model provides a kind of high-protection level combined type anticollision barrier, mostly be the reinforced concrete fence structure to solve existing guardrail than high-protection level, pattern is stiff, can not adapt to the technical problem of high-risk highway section to guardrail protective capacities, view, easy to maintenance etc. high standard instructions for use.
A kind of high-protection level combined type anticollision barrier described in the utility model is made up of the post and beam guardrail on top and the reinforced concrete fence of bottom; Described top post and beam guardrail is by column, crossbeam, overarm brace and be connected base plate and form; The section of described column is a frame construction, inner transverse is fixed with the column floor, and described crossbeam section is a frame construction, and this crossbeam upper surface is concordant with the column upper surface, the cover plate that is connected that is positioned on crossbeam upper surface and the column upper surface is fixed together crossbeam and column by bolt; Between crossbeam lower surface and stud sides end face, realize reinforcing the connection by an overarm brace and bolt; The lower rebar concrete guardrail is made up of pre-embedded bolt, pre-embedded steel slab and reinforced concrete wall; The lower surface of described column is connected and fixed by pre-embedded bolt and the pre-embedded steel slab that is embedded in the reinforced concrete wall upper surface for connecting base plate.
Described crossbeam is two-layer or multilayer, connects by support respectively with connecting bolt between each crossbeam lower surface and the stud sides end face, and the cross section of every layer of crossbeam is half degree of lip-rounding, and the opening part that is positioned at crossbeam forms reinforcement by the crossbeam floor that vertically is provided with.
Connecting bolt between described column, crossbeam and the overarm brace comprise between set bolt between crossbeam upper surface and the column upper surface, stud sides end face and the overarm brace side end face set bolt with pass simultaneously be connected cover plate, the upper and lower end face of crossbeam will be connected the set bolt that cover plate, crossbeam and overarm brace are fixed with the overarm brace upper surface.
The cross section of described crossbeam is square, circular or oval.
The cross sectional shape of described column is a H shape, I-shaped or square, and welding column floor.
The connected mode of described upper metal post and beam guardrail and lower rebar concrete guardrail is welding.
Guardrail lower rebar concrete wall are that the F type is domatic towards the domatic form of road direction.
The advantage of the utility model high-protection level combined type anticollision barrier is: because its anti-collision level reaches 630kJ, can effectively stop oversize vehicle run-off-road, reduce the generation and the economic loss of particularly serious accident.Simultaneously, characteristics such as having reasonable in design, simple and direct, good looking appearance, be easy to construction, the life-span is long, maintenance cost is little can be used for the security protection in highway high-risk highway section.
